Further, by providing the pattern image printing device 15 in which the longitudinal direction of the liquid crystal display board 100 is the width direction of the printing paper 16, the pattern image can be printed on the lower side or the upper side of the vertically long print. In this case, as the input data, data indicating the portrait orientation and the landscape orientation at the time of printing (in the case of a camera capable of inputting the camera attitude data at the time of shooting, the data is recorded in the magnetic recording layer. The vertical and horizontal data are sometimes recorded in the LSI card 49.), so that the pattern image can be automatically printed on the lower side or the upper side of the vertically long print.

If the position data for printing the pattern image, for example, the data indicating the right side, the left side, the center, or the data indicating the print size (L size, panoramic size, powerful wide size, etc.) is included in the input data. Even if print sizes are mixed, the pattern image can be aligned and printed at the position.

Further, in order to make the pattern image easy to see, it is also possible to print the pattern image on the lowest density portion of the printed main image. In this case, a plurality of pattern image printing candidate areas are set in advance in the main image printing area of the photographic printing paper 16 (for example, upper side, lower side, upper right side, upper left side, lower right side of print, (Lower left side, etc.), detecting the density of the image portion of the photographic film 31 corresponding to each candidate area with a color image area sensor,
The position data corresponding to the portion with the lowest density in the main image when printed is input to the control unit 68, and the liquid crystal display panel 100 displays the portion with the lowest density in the main image when printed. The pattern image is displayed on the corresponding part.

When the filament type lamp 100 is used as the light source 106, the shutter device 102 is provided to cut off the afterglow, but when the light emission signal becomes zero, the characters displayed on the liquid crystal display plate 100 are displayed. The liquid crystal display panel 100 can be used in place of the shutter device 102 by erasing it to make it black.

Further, the filament type lamp 100
Alternatively, a strobe light may be used, and the shutter device 102 is not necessary in this case as well.

The liquid crystal display panel 100 may be of a type other than the matrix type as long as it can display characters, and may be of the segment type, for example.

Further, the liquid crystal display panel 100 may be one in which dots are arranged in a line. In this case, the longitudinal direction of the liquid crystal display board 100 is oriented in a direction intersecting the conveyance direction of the photographic paper 16, and the pattern image of the dot pattern is main-scanned by the liquid crystal display board 100 to convey the photographic paper 16 at a predetermined speed. Then, by sub-scanning, it is possible to print on the photographic printing paper 16.

In the above embodiment, the pattern image is printed from the photosensitive surface side of the printing paper 36. However, if the base of the printing paper 16 transmits light, the pattern image printing device 15 is set on the base side. It is also possible to print the pattern image from the side opposite to the photosensitive surface.

Further, in the above embodiment, the example in which the present invention is applied to the printer is shown, but the present invention can also be applied to a printer processor of a minilab or the like.
